AN INORGANIC/ORGANIC COMPOSITE SUPPORT INCLUDES AN INERT INORGANIC MATERIAL, A COMPLEX COMPOUND COMPOSED OF A POLYLOL AND A MAGNESIUM HALIDE, AND AN ORGANIC POLYMER CONTAINING A POLAR FUNCTIONAL GROUP. SAID COMPLEX COMPOUND LOADED WITH THE ORGANIC POLYMER IS DEPOSITED ON THE INERT INORGANIC MATERIAL. WHEN THE INORGANIC/ORGANIC COMPOSITE SUPPORT USED AS A POLYOLEFIN CATALYST CARRIER IS APPLIED TO ETHENE OR PROPYLENE POLYMERIZATION, THE FUSION-FLOW RATIO OF THE OBTAINED POLYMERISATE IS REMARKABLY INCREASED AND ITS PROCESSING PERFORMANCE IS IMPROVED. WHEN THE CATALYST IS APPLIED TO ETHENE POLYMERIZATION, THE FUSION-FLOW RATIO OF THE POLYMERISATE CAN BE ADJUSTED BY CHANGING THE CONTENT OF HYDROGEN. WHEN THE CATALYST IS APPLIED TO ETHENE OR PROPYLENE POLYMERIZATION, THE CATALYST ACTIVITY IS HIGH. |
